Definitions

  • the present invention relates to an improved chassis for a vehicle.
  • Public works machines such as hydraulic shovels, comprise chassis which, up to the present, most wide-spread technique, are monobloc.
  • a continuous increase is furthermore observed in the dimensions of said machines and consequently an increase in the dimensions of their chassis. Displacements of the machines between sites are seriously hindered by these increases and there are manufacturing and mechanical resistance problems which are not easily solved.
  • the invention relates to a chassis for a vehicle intended for carrying heavy loads, particularly for a public works machine with a pivoting turret, comprising two parallel longitudinal members to which at least one transverse frame is fixed.
  • the means for fixing the transverse frame on a longitudinal side member are constituted on the one hand by two swivel joints whose swivel axes, located substantially in line with each other, are parallel to the longitudinal axis of the longitudinal members and on the other hand by two tie-rods pivoted at one end on the frame and an opposite end on one of the longitudinal members.
  • the joints of the tie-rods on the frame and the longitudinal members are parallel to the longitudinal axis of the longitudinal members.
  • FIG. 1 is a partial view, in perspective, of a chassis in accordance with the invention
  • FIG. 2 is a plan view of a chassis according to the invention.
  • FIG. 3 is a section along III--III of FIG. 2;
  • FIG. 4 is a section along IV--IV of FIG. 1;
  • FIG. 5 is a section along V--V of FIG. 2;
  • FIG. 6 is a section along VI--VI of FIG. 2.
  • FIG. 1 the Figures show the chassis of a hydraulic shovel, constituted by three separate elements assembled together: a central transverse frame 1 and two longitudinal side members 2, which extend parallel in the same direction 3.
  • the transverse frame 1 is fixed to each longitudinal member 2 on the one hand by two swivel joints 4 and on the other hand by two tie-rods 5 which are coupled by pivot pins 6 to said frame 1 and each longitudinal member 2.
  • the two spherical swivel joints 4 of the same longitudinal member are aligned in a direction 7 parallel to the direction 3 of said longitudinal member.
  • Each is constituted by a spherical half-bearing 8 welded on the longitudinal member 2, by a bearing cap 9 which is removably fixed to the half-bearing 8 by screws 10, by a spherical swivel joint 11 which is contained in the housing formed by said half-bearing 8 and bearing cap 9, and by two extensions 12 of the swivel joint 11, on which lugs 13 fast with the frame 1 are pivoted.
  • a pivot pin 6 is mounted in the holes 14 made in two lugs 15 welded on the longitudinal member 2 or on the frame 1.
  • the eye 16 constituting the end of the tie-rod 5 is mounted to rotate on pin 6.
  • the pivot axis 17 is parallel to direction 3.
  • the frame 1 is fixed to each longitudinal member 2 by two systems of triangulated connections, each constituted by a swivel joint 4 and two pins 6.
  • the resulting assembly therefore possesses the desired rigidity.
  • the "dismountable" feature of the swivel joints 4 and the pins 6 facilitates both assembly and dismantling, this rendering possible the displacements on the highway of large public works machines, after dismantling.
  • the swivel joints 4 have the following functions:
  • the tie-rods 5 have the following functions:
  • One swivel joint 4 out of two is mounted to slide, in order to allow a simple assembly and not to produce any stress by the deformations of the central frame 1.
  • two tie-rods 5 out of four are advantageously adjustable, for example by means of a device with eccentric rings contained in the holes for fixing the tie-rod or the frame.
